The effect of hand-foot exercises on chemotherapy-induced peripheral neuropathy-related pain, falls, and quality of life in colorectal cancer: A randomized controlled trial

PURPOSE

The aim of this study is to determine the effect of hand-foot exercises on chemotherapy-induced peripheral neuropathy-related pain severity, falls, and quality of life in patients with colorectal cancer.

METHODS

The study was conducted in the outpatient chemotherapy unit of a public hospital between 25 April-31 December 2022. The enrolled 39 patients were randomly assigned to the intervention (n:19) and control (n:20) groups. The hand-foot exercises program was applied to the intervention group in three sessions a day and three days a week fashion for 8 weeks at home. No intervention was applied to the control group other than routine treatment and care. Data were collected through face-to-face interviews in the first interview and the 2nd, 4th, 6th, 8th weeks. The exercise program adherence of the intervention group was followed up through telephone/face-to-face interviews in weeks 1-8. Data were collected using the Numerical Pain Rating Scale, Fall Follow-Up Form, the CIPNAT scale, EORTC QLQ-C30 and EORTC QLQ-CR29 scales. Mann-Whitney U Test, Chi-square test, Wilcoxon signed test, and Friedman test were used to analyze the data.

RESULTS

The study found that as of week 4th, the intervention group experienced less pain severity than the control group (p < 0.001); at week 8th, the peripheral neuropathy symptoms of the intervention group decreased compared to the control group (p < 0.05); at weeks 2nd,4th,6th,8th, there was no statistically significant difference in falls (p > 0.05); at week 8th, while there was no significant difference between the groups regarding colorectal cancer quality of life (p > 0.05), the overall cancer quality of life improved in the intervention group (p < 0.05).

CONCLUSIONS

The hand-foot exercises program is effective in chemotherapy-induced peripheral neuropathy-related symptoms, pain severity, and overall cancer quality of life.

Topical menthol for chemotherapy-induced peripheral neuropathy: a randomised controlled trial in breast cancer

OBJECTIVES

Chemotherapy-induced peripheral neuropathy (CIPN) symptom is one of the side effects of paclitaxel in breast cancer patients. This randomised controlled study was conducted to investigate the effect of topical menthol applied on the hands and feet of breast cancer patients receiving chemotherapy on CIPN symptoms.

METHODS

60 breast cancer patients receiving chemotherapy were randomly assigned to an intervention group (n=30), which received topical menthol treatment, or a control group (n=30), which received standard care. Both groups continued their routine pharmacological treatments throughout the study. The intervention group applied 1% menthol topically to their hands and feet two times a day. The effect of the intervention on CIPN symptoms was evaluated 3 weeks and 6 weeks after the intervention.

RESULTS

The intervention group showed a significantly greater improvement in CIPN symptoms over time compared with the control group, with an effect size of η2=0.214 for the group×time interaction. Additionally, the intervention group exhibited a notable positive change in the exposure subscale of the CIPN rating scale, with an effect size of η2=0.114.

CONCLUSIONS

Topical application of menthol significantly mitigates the symptoms of CIPN in breast cancer patients. This study supports the use of menthol as an effective adjunctive treatment for CIPN.

Peripheral neuropathy and lifestyle factors in women with breast cancer receiving taxane-based chemotherapy: Pathway analysis

PURPOSE

Peripheral neuropathy adversely affects the treatment process of cancer, and thus it is important to reveal the factors leading to peripheral neuropathy and to take the necessary precautions to avoid it. This study was conducted to investigate the relationship between chemotherapy-induced peripheral neuropathy (CIPN) and lifestyle factors (nutrition, physical activity and sleep quality).

METHODS

This descriptive and correlational study was conducted with 108 individuals who were treated in the chemotherapy unit of a hospital between April 2021 and April 2022 in Turkey. Data were collected using the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT), the International Physical Activity Questionnaire (IPAQ), the Mini Nutritional Assessment Test (MNA), and the sleep level Visual Analog Scale. Number, percentages, means, and standard deviations were calculated, and multiple linear regression analysis and path analysis were conducted to analyze the data.

RESULTS

The results indicate that the total MET score significantly and positively predicted the sleep scale score (β = 0.24, p < 0.01), while it negatively and significantly predicted the CIPNAT score (β = -0.30, p < 0.001). In addition, both the MNA screening score and the sleep scale score significantly and negatively predicted the CIPNAT score (β = -0.25, p < 0.01, β = -0.29, p < 0.001, respectively).

CONCLUSIONS

Lifestyle factors (exercise, nutrition, sleep) were found to have an effect on peripheral neuropathy. It is thought that increasing the level of exercise improves sleep quality, and regular nutrition, quality sleep and increased physical activity may be effective in reducing peripheral neuropathy.

Assessing chemotherapy-induced peripheral neuropathy with patient reported outcome measures: a systematic review of measurement properties and considerations for future use

PURPOSE

Chemotherapy-induced peripheral neuropathy (CIPN) is a common toxicity of cancer treatment, with potential to significantly impact cancer survivors' long-term quality of life. Patient reported outcome measures (PROMs) are increasingly utilised to evaluate CIPN. However, guidance remains lacking on how to identify fit for purpose PROMs with considerations necessarily differing when used in various research and in-clinic contexts. This study aimed to evaluate evidence about CIPN PROMs measurement properties and propose considerations to optimize CIPN PROM selection for each purpose.

METHODS

A systematic review was conducted to identify literature assessing measurement properties of CIPN PROMs. These were evaluated against Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria and International Society for Quality of Life minimum standards. Risk of Bias (RoB) was assessed using the COSMIN RoB checklist.

RESULTS

Thirty-nine papers evaluating measurement properties of 13 PROMs were included. The European Organization for Research and Treatment of Cancer Quality of Life Chemotherapy-Induced Peripheral Neuropathy Questionnaire (QLQ-CIPN20) and Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) were the most commonly investigated PROMs and had the most measurement properties meeting established criteria.

CONCLUSION

The use of the QLQ-CIPN20 and FACT/GOG-Ntx to assess CIPN in research settings has the most supporting evidence. However other considerations including study aims, endpoints and target population also factor into PROM selection and need to be considered more often when determining the most suitable outcome measure. Evidence of CIPN PROMs use in clinical practice is limited and their adoption to individual-patient level management requires more evaluation.

Psychometric Properties of the Korean Version of the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool

BACKGROUND AND PURPOSE

Chemotherapy-induced peripheral neuropathy (CIPN) is a multidimensional symptom cluster induced by neurotoxic chemotherapy agents among patients with cancer. A well-developed tool for assessing CIPN can help with the early detection and timely management of patients. This study assessed the reliability and validity of the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT) in Korean women with breast cancer who were treated with chemotherapy.

METHODS

A psychometric analysis of the Korean version of CIPNAT was conducted with 207 patients with breast cancer who were treated with chemotherapy. Patients were assessed using the CIPNAT and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy-20 (CIPN-20). Analyses of internal consistency reliability, concurrent validity, and construct validity (based on structural and discriminant validity testing) were performed to evaluate the psychometric properties.

RESULTS

The Korean version of the CIPNAT had good internal consistency (Cronbach's alpha = 0.95; the item-total correlation coefficients ranged 0.34-0.76). The CIPNAT and CIPN-20 were moderately correlated (r = .67). Confirmatory factor analyses showed a four-factor structural model with acceptable model fit indices. Discriminant validity was supported by differences between individuals treated with and without taxane-based chemotherapy (p < .001).

IMPLICATIONS FOR PRACTICE

The Korean version of the CIPNAT was a valid and reliable screening tool for identification of CIPN symptoms and functional interference in Korean women who received chemotherapy for breast cancer. The instrument can be useful for the timely and routine assessment of CIPN symptoms and functional limitations of patients with cancer by oncology nurses.

Clinical and biochemical markers in CIPN: A reappraisal

The increased survival of cancer patients has raised growing public health concern on associated long-term consequences of antineoplastic treatment. Chemotherapy-induced peripheral neuropathy (CIPN) is a primarily sensory polyneuropathy, which may be accompanied by pain, autonomic disturbances, and motor deficit. About 70% of treated cancer patients might develop CIPN during or after the completion of chemotherapy, and in most of them such complication persists after six months from the treatment. The definition of the potential risk of development and resolution of CIPN according to a clinical and biochemical profile would be certainly fundamental to tailor chemotherapy regimen and dosage on individual susceptibility. In recent years, patient-reported and clinician-related tools along with quality of life instruments have been featured as primary outcomes in clinical setting and randomized trials. New studies on metabolomics markers are further pursuing accurate and easily accessible indicators of peripheral nerve damage. The aim of this review is to outline the strengths and pitfalls of current knowledge on CIPN, and to provide a framework for future potential developments of standardized protocols involving clinical and biochemical markers for CIPN assessment and monitoring.

The preliminary effects of henna on chemotherapy-induced peripheral neuropathy in women receiving oxaliplatin-based treatment: A parallel-group, randomized, controlled pilot trial

PURPOSE

Chemotherapy-induced peripheral neuropathy (CIPN) may frequently occur in patients receiving oxaliplatin-based treatment. The aim of the present parallel-group, randomized, controlled pilot trial was to investigate the effect of henna on CIPN in women receiving oxaliplatin-based treatment.

METHOD

Sixty female patients receiving oxaliplatin-based treatment were randomly divided into two groups, i.e., one intervention group (n = 30) where henna was applied topically and one control group (n = 30) that received routine treatment and care. Women in the intervention group were provided a pack of henna prepared by the investigators following each treatment course (2nd, 3rd, and 4th courses) and were instructed to apply the henna on their palms, fingers, and soles. The chemotherapy-induced peripheral neuropathy assessment tool (CIPNAT) was completed by women subsequent to the 2nd (baseline), 3rd, and 4th courses of treatment.

RESULTS

The intragroup assessment performed for the intervention group revealed that the total CIPNAT score significantly declined in the intervention group (p < 0.05). The score changes by time in the intervention and control groups were in favour of the intervention group, and the effect size for group × time interaction was η² = 0.169. Similarly, regarding the symptoms intervention section of the tool, a positive change by time in the intervention group was observed, and the effect size concerning this change was large, i.e., η² = 0.284.

CONCLUSIONS

The present study results showed that henna application on hands and feet has a beneficial effect on peripheral neuropathy. Applying henna is a promising approach in CIPN management.

Validation of the Arabic Version of the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool

BACKGROUND

Chemotherapy-induced peripheral neuropathy results in multidimensional neurological and muscular symptoms, which interfere with the patients' daily life.

AIM

Examine the psychometric properties of the Arabic version of the chemotherapy-induced peripheral neuropathy assessment tool (CIPNAT) among adult cancer patients.

METHOD

A descriptive study design was used. A convenience sample of 210 patients was assigned to two groups: 135 who received chemotherapies of known neurotoxic potential and 75 who served as a comparison group. Translation and back-translation considering cross-cultural issues to produce the Arabic version of CIPNAT was used. Test-retest and internal consistency reliability were used to test the reliability of the tool, whereas for the validity, content and construct validity were assessed.

RESULTS

Test-retest scores for the overall scale (r = 0.98, p = < .001), for the symptom experience subscale (r = 0.97, p = <.001), and for the interference subscale (r = 0.96, p = < .001) all showed evidence of reliability. Cronbach α coefficients were 0.97, 0.96, and 0.95 for the total scores, symptoms experience, and interference scales, respectively. Items to total correlation ranged from moderate to strong (0.55-0.81). The Content Validity Index was 0.83. The data support the evidence of discriminant validity, as significant differences were found between the groups with regard to symptom experience (t = 8.51, p = < .001), interference (t = 5.60, p = <.001), and total score (t = 7.88, p = < .001).

CONCLUSIONS

The Arabic version of CIPNAT showed adequate reliability and validity to screen for chemotherapy-induced peripheral neuropathy symptoms and their interference in Arab countries. Further studies are needed to evaluate concurrent validity.

Overview and critical revision of clinical assessment tools in chemotherapy-induced peripheral neurotoxicity

Chemotherapy-induced peripheral neurotoxicity (CIPN) is a major toxicity of cancer treatment, leading to dose reduction and premature treatment cessation, potentially affecting patient function, and quality of life. The development of accurate and sensitive assessment tools for CIPN is essential to enable clinical monitoring during treatment, follow-up of long-term outcomes and measurement of toxicity in clinical trials. This review examines CIPN clinical assessment scales incorporating clinician-based, composite, and patient-reported outcomes (PROs), providing a systematic review of their properties and an updated critical analysis of recommendations on current evidence for their use. This systematic review of CIPN assessment tools identified 50 papers containing 41 assessment tools, across 4 categories (common toxicity criteria; composite neurological scale; PROs; pain scale). The majority of these tools were PROs, underscoring the importance of patient-based assessment of symptoms. While there has been considerable work in the field over the past 10 years, this review highlights significant gaps, including a lack of evaluation of responsiveness and problematic neuropathic pain evaluation. There remains a need for consensus on the best available tool and the need to modify existing instruments to improve utility.

Reliability and Validity of the Turkish Version of Chemotherapy-induced Peripheral Neuropathy Assessment Tool for Breast Cancer Patients Receiving Taxane Chemotherapy

Objective:

The aim was to evaluate the reliability and the validity of the Turkish version of the chemotherapy-induced peripheral neuropathy assessment tool (CIPNAT) in cancer patients using taxane.

Methods:

This methodological study was carried out to evaluate the validity and the reliability of the CIPNAT. The sample cohort comprised 430 breast cancer patients who were administered taxane, a chemotherapeutic agent, between April and December 2017. Data were collected by the CIPNAT and by a demographic data form. The CIPNAT content reliability was checked after completing it in Turkish. Validity was tested after the translation as well. Cronbach's alpha and test–retest reliability were utilized for reliability analyses.

Results:

Cronbach's alpha value was 0.87 in this study. The test–retest reliability ranged between 0.90 and 0.96 for all items. No difference existed between the means of test and retest scores of the CIPNAT. A statistically significant positive relationship materialized between the item's test and retest scores. There were statistically significant positive relationships among all levels of the CIPNAT. Factor analysis resulted in a size value higher than 1 and explained 66% of total variation. These results show that the Turkish version of the CIPNAT is a valid and reliable scale in Turkish society.

Conclusions:

This study showed that the CIPNAT in Turkey is a reliable and valid tool to evaluate taxane chemotherapy in breast cancer patients.
